REO Speedwagon and Imagine Dragons Joined Forces to Play 'Roll With the Changes' on Kimmel

Just call them REO SpeedDragons.

Though we're not sure anything will ever top Warren and Kenny G, Jimmy Kimmel Live!'s occasional band mash-ups are always a treat. The aforementioned rapper and sax man are more or less contemporaries, but last night it was the old school meeting the new school as REO Speedwagon shared the stage with Imagine Dragons to form, yes, REO SpeedDragons.

Because an Imagine Dragons song would probably be a little too intense for the much-older members of the relatively mellow REO Speedwagon, the new supergroup opted to play Speedwagon's 1978 hit "Roll With the Changes." Despite Kevin Cronin's voice having lost a little horsepower over the years—a YouTube commenter was spot on in saying he thought something was wrong with his speakers when the Speedwagon frontman started singing—the performance was actually pretty awesome, culminating with a kickass inter-generational jam.
